so my 1998 mx5 nb engine finally had a problem its leaking water from behind the intake manifold directly above the 2 sensors near the oil cooler
so when i get the intake off i will know for sure
leak slows greatly when block heats up
suspecting head gasket
my block also uses 1l of oil per 2 tanks of gas
was thinking new block and head built for turbo application
http://racingmazda.com/product/miata-block/
with the cp piston 9-1
stock head to start
order the fm 1999-00 FM turbo kit - no electronics with gt3071r
g4 plug and play ecu
deuthwerks 340l/hr fuel pump
things i have not planned yet
head gasket thickness
larger injectors that fit factory stuff
weather the stock o2 sensor is ok (4 wire atm i think)
aftermarket oil pump / more pressure?
anything else i may have missed engine wise?

Sounds extreme. Out of interest, what year car and what engine do you have?
Turbo kit suggestion suggests NB8A, engine suggests NB8C?
Stock O2 sensor is narrowband. You'll need to replace with a wideband, but when you're spending that much money on a turbo and built engine, getting one will be the least of your worries $$$-wise.
